RESUMEN
OBJECTIVE:To establish a method for the identification of Chongqing local medicinal material Heracleum hemsley-anum. METHODS:The original plant morphology,morphological characteristics,microscopic characteristics (transverse section and powder),were identified. RESULTS:H. hemsleyanum had cone shape root,brown,many-branched with special fragrance;the microscopic characteristics of taproot a transverse showed no differences with lateral root transverse section,primary xylem was di-arch,secondary phloem was more developed than secondary xylem,secondary phloem was rich in the oil chamber.
